Description

  The present invention relates to a packing material used for packing an article to be packed.

  2. Description of the Related Art Generally, a packaging material used for packaging an electrical appliance such as an image forming apparatus and its components is configured by bonding and fixing a cushioning member made of foamed polystyrene or the like to a thick paper such as cardboard with an adhesive or the like. Here, in recent years, paper products such as corrugated cardboard and foamed resin products such as expanded polystyrene are increasingly used for reuse or recycling (hereinafter referred to as “reuse”). In order to appropriately reuse the paper product, it is necessary to properly separate the paper product and the foamed resin product.

  However, it is difficult to separate the foamed resin product that is adhesively fixed to the paper product. In order to solve such a problem, a notch hole or notch is provided in a part of the pad mounting surface portion (the portion where the buffer member is mounted) of the plate-like support member, and this pad mounting surface portion is inserted into the mold. There is known a packaging material provided with a cushioning member formed by foaming beads by a special molding method (so-called outsert molding method) for holding (see, for example, Patent Document 1). In this packaging material, the buffer member is formed so that the support member is attached from the front and back in a continuous manner at a portion such as a notch hole. Since the buffer member has a small cross-sectional area at a continuous portion at a notch hole or the like and is a foamed bead molded body, the buffer member can be easily divided between the front and back of the support member. Thereby, the buffer member can be easily separated from the support member.

JP-A-5-178372

  However, in the conventional packaging material described above, when the buffer member is separated from the support member, the buffer member has to be broken (divided), and thus there is a problem that the separated buffer member cannot be reused.

  Moreover, in the above-mentioned conventional packing material, the material of the buffer member is limited. For example, the buffer member formed of corrugated cardboard or the buffer molded by a manufacturing method (injection molding, extrusion molding, etc.) other than foam bead molding. The member cannot be used, and the degree of freedom of the combination of the material of the buffer member and the support member is limited. For this reason, there existed a problem that the optimal packing material could not be applied according to the kind of to-be-packaged object.

  Furthermore, in the above-described conventional packing material, since the buffer member is formed by a special molding method, there is a concern that the cost may be increased and the molding position of the buffer member on the support member may be restricted.

  The present invention has been made to solve the above-described problems, and provides a packing material that can easily and inexpensively separate a buffer member and a support member and can appropriately protect an object to be packed. It is intended to do.

  In order to achieve the above-described object, the packing material of the present invention includes a buffer member that abuts on an object to be packed, and a support member that supports the buffer member, and the buffer member is formed through the support member. And an insertion restricting portion that is provided continuously to the insertion portion and restricts the insertion of the insertion portion into the opening of the support member.

According to this configuration, the insertion of the buffer member into the opening is restricted by the insertion restricting portion provided continuously with the insertion portion by inserting the insertion portion from one of the openings opened in the support member. In the state, it is supported by the support member. That is, the buffer member is not restricted from moving in the direction of extraction from the opening, and can be extracted from the opening without destroying the buffer member. Accordingly, the buffer member can be appropriately supported by the support member, the buffer member and the support member can be easily separated, and the buffer member and the support member can be appropriately reused.
Further, since the buffer member and the support member can be manufactured (molded) separately, the combination of the materials of the buffer member and the support member can be freely set. Thereby, an optimal material can be selected as the packing material according to the manufacturing cost and the type of the object to be packed.
Furthermore, by arbitrarily adjusting the protruding amount of the insertion portion of the buffer member from the opening of the support member, a packaging material that can flexibly cope with a plurality of types of items to be packed having different sizes and shapes is configured. Can do.

  In this case, it is preferable that the support member has at least one protrusion provided so as to protrude toward the inside of the opening.

  According to this configuration, the protruding portion slightly bites into the insertion portion of the buffer member inserted through the opening. Thereby, the insertion part is supported in a stable state by the opening of the support member. Moreover, it can prevent that an insertion part pulls out from an opening part by the said protrusion part biting in.

  In this case, the opening of the support member is formed in an asymmetric shape, and the insertion portion of the buffer member has a cross-sectional shape corresponding to the opening formed in an asymmetric shape. Is preferred.

  According to this configuration, since the shape of the opening of the support member and the cross-sectional shape of the insertion portion of the buffer member are asymmetric shapes corresponding to each other, the orientation of the insertion portion (buffer member) inserted into the opening is , Decide uniquely. Thereby, since the operator can recognize the insertion direction of the insertion part (buffer member) accurately at a glance, the operator can prevent the insertion part from being inserted into the opening in the wrong direction ( (Incorrect insertion prevention). This is particularly effective when, for example, an insertion portion (buffer member) having a plurality of sizes and shapes is inserted (inserted) into a plurality of openings corresponding thereto.

  Further, in this case, the packing materials are respectively disposed on the peripheral side surfaces of the article to be packed, and each of the support members is a plate-like member, and adjacent to both end portions of each of the support members. It is preferable that a hooking portion is formed to be hooked and connected to the support member disposed on the side face.

  According to this structure, the several packing material each arrange | positioned by the surrounding side surface of the to-be-packaged object is mutually connected by the latching | locking part provided in the both ends of each support member. Thereby, the surrounding side surface of a to-be-packaged object can be protected appropriately.

  In this case, the insertion restricting portion is preferably a flange provided around the proximal end portion of the insertion portion.

  According to this configuration, the buffer member supported by the support member is supported in a state where the insertion portion of the buffer member is inserted into the opening of the support member. In addition to this, the contact area between the buffer member and the support member increases because the insertion restricting portion formed of the flange makes surface contact with the entire periphery of the opening. Thereby, the support member can support the buffer member in a more stable state.

  In this case, it is preferable that the buffer member has one of the insertion portion and the insertion restriction portion in contact with the package object with respect to a portion where the rigidity of the package object is high.

  According to this configuration, since the buffer member is disposed so as to abut on the portion having high rigidity of the package object, the package object in a state of being packed via the buffer member has high rigidity. Supported by part. Thereby, the to-be-packaged object packed via the buffer member can be protected appropriately.

  According to the present invention, the buffer member can be easily extracted from the opening because movement of the support member in the extraction direction from the opening is not restricted. Thereby, a buffer member and a support member can be separated easily. Further, since the buffer member and the support member can be manufactured (molded) separately, the combination of the materials of the buffer member and the support member can be freely set.

  The bottom holding member is, for example, a cardboard formed in a substantially rectangular plate shape, and is disposed on the upper surface of the skid 2. The bottom holding member includes a bottom surface mounting portion (not shown) that serves as a surface on which the object to be packed 11 is mounted, and four upright portions (not illustrated) provided to rise at four corners of the bottom surface mounting portion. (Omitted). A bottom pad 33 for immovably holding the bottom (lower part) of the article 11 to be packed placed on the bottom placing part is fitted into each standing part.

  The outer case 4 is assembled, for example, by folding a corrugated cardboard into a rectangular cylindrical shape, and forms the appearance of the packaging assembly 1. The opening of the upper surface of the rectangular cylindrical outer case 4 can be closed. In addition, the rectangular cylindrical outer case 4 has an open bottom surface (lower surface), and is configured so as to be able to store the object to be packed 11 by covering from the upper side of the inner packing member 5 containing the object to be packed 11. Yes. A plurality of second connection openings 41 are formed at positions corresponding to the first connection openings 22 of the skid 2 at the lower end portion of the outer case 4. When the outer case 4 is covered from above, the lower end of the outer case 4 enters the inside of the skid 2 formed in a tray shape. The outer case 4 is fixed with respect to the skid 2 by inserting the connecting members 42 in alignment with the positions of the first connecting openings 22 of the skid 2 and the second connecting openings 41 of the outer case 4. The

  As shown in FIG. 2, the inner packing member 5 includes a front side pad 6 a as a packing material for protecting the front side surface of the article 11 to be packed and a rear side portion as a packing material for protecting the rear side face of the item 11 to be packed. The pad 6b, the left side pad 6c as a packaging material for protecting the left side surface of the article 11 to be packed, the right side pad 6d as the packaging material for protecting the right side surface of the article 11 to be packaged, And an inner case 51 that covers the outer sides of the side pads 6a, 6b, 6c, and 6d that are in contact with the peripheral side surface (four surfaces in the present embodiment).

  The inner case 51 is assembled by, for example, folding cardboard into a rectangular cylinder. The inner case 51 is configured to be able to store an object 11 to be packed with the side pads 6a, 6b, 6c, and 6d in contact therewith.

  Next, each side pad 6a, 6b, 6c, 6d as a packing material will be described in detail. FIG. 3 is a perspective view of the buffer member 61 according to the present embodiment. FIG. 4 is a front view of the support member 71 of the front side pad 6a according to the present embodiment. FIG. 5 is a front view of the support member 71 of the rear side pad 6b according to the present embodiment. FIG. 6 is a front view of the support member 71 of the left side pad 6c according to the present embodiment. FIG. 7 is a front view of the support member 71 of the right side pad 6d according to the present embodiment. FIG. 8 is a plan view showing a part of the inner packing member 5 according to the present embodiment.

  As shown in FIG. 2, each side pad 6a, 6b, 6c, 6d has a different shape, but the members constituting each side pad 6a, 6b, 6c, 6d are the same. The members common to the side pads 6a, 6b, 6c, 6d will be described below. In the following description, in the case of the description common to the side pads 6a, 6b, 6c, 6d, only numerals for arithmetic purposes are attached. Each side pad 6 includes a plurality of buffer members 61 that abut against the article to be packed 11 and a support member 71 that supports each buffer member 61.

  As shown in FIGS. 2 and 3, each buffer member 61 is made of a synthetic resin material containing bubbles such as foamed polystyrene. Each buffer member 61 includes a member having a different size and shape depending on a contact position with respect to the article 11 to be packed. Each buffer member 61 is provided to be connected to an insertion portion 62 that passes through an opening 72 (details will be described later) formed through the support member 71, and the insertion portion 62. And an insertion restricting portion 63 that restricts the insertion of the insertion portion 62. In FIG. 2, the buffer member 61 of the rear side pad 6b is not shown.

  The insertion part 62 is formed in a substantially rectangular parallelepiped shape. The insertion portion 62 has an asymmetric cross section (cross section in a direction perpendicular to the insertion direction of the support member 71 into the opening 72). Specifically, for example, the cross section of the insertion portion 62 is a pentagon with one corner of a quadrangle chamfered (see (a) and (b) in FIG. 3) or one side of the quadrangle. Some of them have a protruding shape (see (c) in FIG. 3). Further, (a) and (b) shown in FIG. 3 are not only different in length but also different in the position of one chamfered corner. In addition, the cross-sectional shape of the insertion part 62 should just be an asymmetrical shape, and is not limited to said shape. In the present embodiment, the front side pad 6a, the rear side pad 6b, and the right side pad 6d are configured such that the front end surface of the insertion part 62 comes into contact with the article 11 to be packed. Further, the insertion portions 62 of the respective buffer members 61 have different lengths in the insertion direction into the opening 72 because the distance between the support member 71 and the contact portion of the article to be packed 11 differs depending on the arrangement position on the support member 71. It contains something different.

  The insertion restriction portion 63 is provided integrally with the insertion portion 62. Specifically, the insertion restriction portion 63 is a flange formed on the entire circumference of the proximal end portion of the insertion portion 62 with respect to the insertion direction into the opening 72. That is, the insertion restricting portion 63 is formed larger than the insertion portion 62 and the opening 72, and cannot be inserted into the opening 72. Note that the insertion restricting portion 63 of each buffer member 61 is formed such that the length in the insertion direction to the opening 72 is shorter (thinner) than the insertion portion 62 of each buffer member 61. In the present embodiment, the insertion restricting portion 63 comes into contact with the article to be packed 11 for the left side pad 6c.

  As shown in FIGS. 4 to 7, the support member 71 of each side pad 6 is, for example, cardboard (made of paper) formed in a substantially rectangular plate shape. In the support member 71, a plurality of openings 72 through which the insertion portions 62 of the respective buffer members 61 are inserted are formed so as to penetrate in the thickness direction of the plate of the support member 71. Each opening 72 is formed in an asymmetric shape so as to correspond to the cross-sectional shape of the insertion portion 62 of each buffer member 61 described above. Moreover, each opening 72 is opened so that it may become a dimension substantially the same as the cross section of the insertion part 62 of the corresponding buffer member 61. FIG. Furthermore, each opening 72 is formed at a position where the buffer member 61 comes into contact with a portion having high rigidity of the article 11 in consideration of appropriate protection of the article 11 to be packed. In other words, each buffer member 61 supported by the support member 71 comes into contact with a highly rigid portion of the article 11 to be packed.

  Each opening 72 is provided with a plurality of protrusions 73 protruding slightly (about 1-2 mm) toward the inside thereof. The plurality of protrusions 73 bite into the peripheral surface of the insertion part 62 of the buffer member 61 that has been inserted (penetrated) through the opening 72.

  Further, the side portions adjacent to each other when the side pads 6 are disposed on the front, rear, left and right side surfaces of the object to be packed 11 at both the left and right ends or the front and rear ends of the support member 71 of each side pad 6. Engaging portions 74 for connecting the pads 6 to each other are formed. Specifically, the front side pad 6a and the rear side pad 6b have a pair of slit-shaped engaging portions 74 having upper ends opened at the upper portions of the left and right direction both ends, and a slit-shaped opening at the lower portion of the left end portion. Two hook portions 74 are formed (see FIGS. 4 and 5). The left side pad 6c is formed with two hook-shaped engaging portions 74 having lower ends opened at the upper and lower portions at both ends in the front-rear direction (see FIG. 6). Further, the right side pad 6d is formed with a pair of hook-shaped engaging portions 74 having lower ends opened at the upper portions of both ends in the front-rear direction (see FIG. 7). The engagement of the side pads 6 by the engagement portions 74 faces the engagement portions 74 of the left side pad 6c and the right side pad 6d with respect to the engagement portions 74 of the front side pad 6a and the rear side pad 6b, This is done by moving each side pad 6c, 6d from top to bottom. Thereby, the side pads 6 adjacent to each other are hooked by the hook portions 74, and the side pads 6a, 6b, 6c, 6d are connected in a rectangular cylindrical shape.

  Furthermore, the support member 71 of each side pad 6 is provided with an arrangement position mark 75 for indicating whether it should be arranged in the front, back, left or right position of the article 11 to be packed. Each arrangement position mark 75 is formed so as to penetrate in the thickness direction of the plate of the support member 71 in the vicinity of the approximate center of the support member 71. Specifically, the arrangement position mark 75 of the front side pad 6a is “F” which is an initial of “Front” (see FIG. 4). Further, the arrangement position mark 75 of the rear side pad 6b is an arrow connecting “R” and “L” which are initials of “Right” and “Left”, and connecting them (see FIG. 5). Similarly, the arrangement position mark 75 of the left side pad 6c and the right side pad 6d is an arrow connecting “F” and “R” which are initials of “Front” and “Rear” (see FIG. 6 and FIG. 6). (See FIG. 7). Further, each placement position mark 75 can be read correctly when viewed from the table when each side pad 6 is correctly placed on the front, back, left, and right side surfaces of the article 11 to be packed. In the following description, the surface on which the arrangement position mark 75 can be read correctly is referred to as “front surface F” of the support member 71, and the opposite surface is referred to as “back surface B” of the support member 71.

  An operator who assembles the packing assembly 1 can dispose each side pad 6 at the correct position of the article 11 by checking the disposition position mark 75. Further, since the worker only has to arrange the side pads 6 on the package 11 in such a direction that the arrangement position mark 75 can be read correctly as viewed from the front, the front and back of the side pads 6 are arranged in error. Can be prevented.

  Then, the assembly procedure of the packaging assembly 1 is demonstrated. First, an operator lays a protective sheet 13 on the upper surface of the article to be packed 11 and covers the bag-shaped cover 12 from above the article to be packed 11. Then, the object to be packed 11 covered with the cover 12 is placed on the bottom holding member laid on the skid 2, and the lower four corners of the object to be packed 11 are fixed by the bottom pad 33.

  Next, the front side pad 6a, the rear side pad 6b, the left side pad 6c, and the right side pad 6d are assembled. For the front side pad 6a, the rear side pad 6b, and the right side pad 6d, the operator inserts the corresponding buffer member 61 from the surface F of each support member 71 into each opening 72 of each support member 71. The part 62 is inserted. Further, for the left side pad 6 c, the insertion part 62 of the corresponding buffer member 61 is inserted into the opening 72 of each support member 71 from the back surface B of each support member 71. As described above, the shape of each opening 72 and the cross-sectional shape of each insertion portion 62 are formed in an asymmetric shape corresponding to each other, and therefore a specific opening 72 has a specific corresponding to this. Only the buffer member 61 having the insertion section 62 having a cross-sectional shape can be inserted. That is, the direction of the insertion part 62 (buffer member 61) inserted into the opening 72 is uniquely determined.

  When each insertion member 62 is inserted into the opening 72, each buffer member 61 is attached to the support member 71 in a state in which insertion into the opening 72 is restricted by the insertion restriction portion 63 provided continuously to the insertion portion 62. Supported. At this time, the plurality of protrusions 73 protruding from the inside of the opening 72 slightly bite into the peripheral surface of the insertion portion 62 of each buffer member 61. Further, the flange-shaped insertion restricting portion 63 is in surface contact with the entire periphery of the opening 72 on the surface F of the support member 71. Thereby, each buffer member 61 is appropriately supported by the support member 71. Each side pad 6 is assembled by inserting the buffer member 61 into all the openings 72 formed in each support member 71 and supporting them appropriately.

  Next, the operator arranges each side pad 6 at the correct position of the article to be packed 11 while confirming the arrangement position mark 75 of each assembled side pad 6 and adjoins the side pads adjacent to each other. 6 hooks 74 are hooked to connect the side pads 6a, 6b, 6c, 6d. Specifically, first, the front side pad 6a and the rear side pad 6b are arranged before and after the article 11 to be packed. Next, the left side pad 6c and the right side pad 6d are faced to the left and right of the article 11 to be packed, and the hooking parts 74 of the side pads 6c and 6d are hooked with the hooking parts 74 of the side pads 6a and 6b. Let In this state, each buffer member 61 of each side pad 6a, 6b, 6c, 6d connected in a rectangular cylindrical shape comes into contact with a predetermined position (a highly rigid portion) of the article 11 to be packed.

  Next, the worker puts the inner case 51 from above the article to be packed 11 around which the side pads 6a, 6b, 6c, 6d are provided. Each side pad 6a, 6b, 6c, 6d is fixed to each side surface of the article 11 and the inner packing member 5 is assembled. Further, the covered inner case 51 can appropriately prevent each buffer member 61 from dropping from the opening 72 of the support member 71. In this state, a gap is formed between each side surface of the object to be packed 11 and the back surface B of the support member 71 and between the surface F of the support member 71 and the inside of the inner case 51. .

  Finally, the operator covers the outer case 4 from above the inner packing member 5 and fixes the outer case 4 to the skid 2 with a plurality of connecting members 42. Thereby, the assembly of the packaging assembly 1 is completed.

  According to the present embodiment, in the buffer member 61, the insertion part 62 is inserted from one of the openings 72 opened in the support member 71, and the insertion to the opening 72 is restricted by the insertion restriction part 63. Thus, it is supported by the support member 71. That is, the movement of the buffer member 61 in the insertion direction (insertion direction) with respect to the opening 72 is restricted by the insertion restriction portion 63. On the other hand, the movement of the buffer member 61 in the extraction direction from the opening 72 is not restricted. Therefore, the buffer member 61 can be extracted from the opening 72 without breaking. That is, the buffer member 61 and the support member 71 can be separated by simply pulling out the insertion portion 62 from the opening 72. Thereby, the buffer member 61 can be appropriately supported by the support member 71, and the buffer member 61 and the support member 71 can be easily separated. For this reason, the reuse etc. of the buffer member 61 and the support member 71 can be performed appropriately.

  Moreover, according to this embodiment, since the buffer member 61 and the support member 71 can be manufactured (molded) separately, the combination of the materials of the buffer member 61 and the support member 71 can be freely set. Thereby, an optimal material can be selected as the side pad 6 (packing material) according to the manufacturing cost and the type of the article 11 to be packed. In the present embodiment, the buffer member 61 is made of a synthetic resin material containing bubbles such as foamed polystyrene. Instead, it has a paper material such as corrugated cardboard and other impact absorbing power. Any material may be used. In the present embodiment, the support member 71 is made of paper cardboard. However, instead of this, any material such as plastic cardboard or wooden or metal may be used. Moreover, you may use combining these materials arbitrarily.

  Furthermore, according to the present embodiment, by arbitrarily adjusting the amount of protrusion of the insertion portion 62 of the buffer member 61 from the opening 72 of the support member 71, it is possible to flexibly adjust a plurality of types of packages 11 having different sizes and shapes. The packaging material which can respond | correspond to can be comprised. Specifically, by arbitrarily adjusting the amount of protrusion of the insertion portion 62 of the buffer member 61 from the opening 72 (back surface B) of the support member 71, each side surface of the article to be packed 11 and the back surface B of the support member 71. Can be set to an arbitrary size. Further, by arbitrarily setting the thickness of the insertion restricting portion 63 (length in the insertion direction), the gap between the surface F of the support member 71 and the inner side of the inner case 51 can be set to an arbitrary size. . In the present embodiment, the insertion restricting portion 63 is formed so that the length in the insertion direction into the opening 72 is shorter (thinner) than the insertion portion 62, and thus the surface F of the support member 71 and the inner case 51. The gap with the inside of the is reduced. For this reason, the inner side packing member 5 (packing assembly 1) can be formed compactly.

  According to the present embodiment, the plurality of protrusions 73 slightly bite into the peripheral surface of the insertion part 62 of the buffer member 61 inserted through the opening 72. Thereby, the insertion part 62 is supported in a stable state by the opening 72 of the support member 71. Further, it is possible to prevent the insertion portion 62 from easily falling off from the opening 72. Note that the number of protrusions 73 is arbitrary, and it is sufficient that at least one or more protrusions 73 are provided. Moreover, in this embodiment, since each opening part 72 is opened so that it may become the substantially same dimension as the cross section of the insertion part 62 of a corresponding buffer member 61, the insertion part 62 of the buffer member 61 is a support member. If it fits in the opening 72 of 71 to such an extent that it does not fall off easily, the protrusion 73 is unnecessary.

  According to the present embodiment, the shape of the opening 72 of the support member 71 and the cross-sectional shape of the insertion portion 62 of the buffer member 61 are asymmetric shapes corresponding to each other, and thus the insertion portion 62 that is inserted into the opening 72. The direction of the (buffer member 61) is uniquely determined. Thereby, since the operator can recognize the insertion direction of the insertion part 62 (buffer member 61) correctly at a glance, it prevents that the insertion part 62 is inserted into the opening part 72 in an incorrect direction. be able to. Further, even when a plurality of insertion portions 62 (buffer members 61) having different sizes and shapes are inserted into the corresponding opening portions 72 as in the present embodiment, the operator can open the insertion portion 62 and the opening portion at a glance. Since the correspondence relationship with the portion 72 can be recognized, the buffer member 61 can be supported at the correct position of the support member 71.

  According to the present embodiment, the side pads 6 a, 6 b, 6 c, 6 d as a plurality of packing materials respectively disposed on the peripheral side surface of the article 11 are provided at both ends of each support member 71. The hooks 74 are connected to each other. Thereby, the surrounding side surface of the to-be-packaged object 11 can be protected appropriately.

  In the present embodiment, the insertion portion 62 of each buffer member 61 is formed such that the length in the insertion direction into the opening 72 is longer (thicker) than the insertion restriction portion 63 of each buffer member 61. Further, in the present embodiment, the left side pad 6 c causes the insertion restricting portion 63 of each buffer member 61 to abut on the article to be packed 11 and causes the insertion portion 62 of each buffer member 61 to protrude from the surface F of the support member 71. ing. For this reason, as shown in FIG. 8, the gap between the surface F of the support member 71 and the inner side of the inner case 51 is formed larger in the left side pad 6c than in the other side pads 6a, 6b, 6d. It will be. By making a large gap between the surface F of the support member 71 and the inner side of the inner case 51, the hooking portion 74 is formed at a position moved from the vicinity of the end of the support member 71 to the center side. Specifically, the left side pad 6c is positioned on the right side (the packaged item 11 side) with respect to the left ends of the front side pad 6a and the rear side pad 6b. For this reason, the front side pad 6a for engaging with the engaging part 74 of the left side pad 6c and the engaging part 74 of the rear side pad 6b are shown in FIG. 8 from the left end of each support member 71 of the side pads 6a, 6b. It is formed at a position separated by A as shown. Thereby, the rigidity of the engaging part 74 on the left side of the side pads 6a and 6b can be increased. In order to increase the rigidity of the engaging portion 74, the thickness of the insertion restricting portion 63 (length in the insertion direction) is increased in the above embodiment without changing the insertion direction of the buffer member 61, and the support member The gap between the surface F of 71 and the inner side of the inner case 51 may be increased.

  According to the present embodiment, the buffer member 61 supported by the support member 71 is supported in a state where the insertion portion 62 penetrates the opening 72 of the support member 71. In addition to this, the contact area between the buffer member 61 and the support member 71 increases because the insertion restricting portion 63 formed of a flange makes surface contact with the entire periphery of the opening 72. Thereby, the support member 71 can support the buffer member 61 in a more stable state. In the present embodiment, the insertion restricting portion 63 is a flange formed on the entire circumference of the proximal end portion of the insertion portion 62. However, the present invention is not limited to this, for example, the proximal end of the insertion portion 62. A protrusion protruding in a circumferential direction from a part of the part may be used. It is sufficient that at least one or more such protrusions are provided. Further, for example, the entire buffer member 61 may be formed in a tapered shape with respect to the insertion direction into the opening 72. In this case, a tapered narrow portion smaller than the opening 72 is inserted into the opening 72, and insertion into the opening 72 is restricted at a portion larger than the opening 72. That is, the insertion restricting portion 63 only needs to have a size or shape that cannot pass through the opening 72.

  According to this embodiment, since the buffer member 61 is disposed so as to abut on the portion of the package object 11 having high rigidity, the package object 11 in a state of being packed via the buffer member 61 is: It is supported at the part where its own rigidity is high. Thereby, the to-be-packaged object 11 packed via the buffer member 61 can be protected appropriately. In the present embodiment, the front side pad 6a, the rear side pad 6b, and the right side pad 6d have the front end surface of the insertion part 62 of each buffer member 61, and the left side pad 6c has each buffer member. The insertion restricting portions 63 of 61 are in contact with the object to be packed 11, but the present invention is not limited to this, and either the insertion portion 62 or the insertion restricting portion 63 is in contact with the object to be packed 11. Just do it.

  In addition, in this embodiment, since the to-be-packaged object 11 was a substantially rectangular parallelepiped, each side pad 6 (packing material) was each arrange | positioned on four side surfaces, However, It is not limited to this, The number of side pads 6 may be increased or decreased according to the shape of the package 11. In the present embodiment, the plurality of buffer members 61 are supported by one support member 71, but one or more buffer members 61 may be supported by the support member 71.

  In addition, since description of embodiment of this invention mentioned above has demonstrated suitable embodiment in the packing material which concerns on this invention, the shape of the side pad 6 and each component of the side pad 6 are demonstrated. There are cases where various technically preferable limitations are applied in terms of the number, installation position, etc., but the technical scope of the present invention is limited to these embodiments unless otherwise specified. is not. Furthermore, the components in the embodiment of the present invention described above can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible. The description of the embodiment of the present invention described above does not limit the contents of the invention described in the claims.
